Arrange the following polymers in decreasing order of their intermolecular forces:Bakelite, Polythene, Buna-S, Nylon-6,6Arrange the following polymers in decreasing order of their intermolecular forces:Bakelite, Polythene, Buna-S, Nylon-6,6 |

Answer» Answer: Hence the decreasing order of intermolecular forces is- BAKELITE > Nylon-6,6> Polythene > Buna-S Explanation: As we know that elastomers (Buna-S) have weak intermolecular forces, FIBRES (Nylon-6,6) have dipole-dipole interaction, thermoplastics (Polythene) have intermolecular forces INTERMEDIATE between elastomers and fibres and thermosetting POLYMERS (Bakelite) undergoes permanent change on heating. |
